Stationary electron vortex states in a plasma bubble field
Hui-Dong Huang, Qi Meng, Zhi-Bin Wang +3
Plasma wakefield accelerators (PWFAs) offer accelerating gradients of 10-100~GV/m and relativistically propagating plasma bubbles capable of confining charged particles. We study t…
Robustness of Off-Axis Electron Vortices in Nonuniform Magnetic Fields
Hui-Dong Huang, Qi Meng, Zhi-Bin Wang +3
Rotational symmetry protects the topological charge of on-axis electron vortices but not of off-axis vortices. We identify an additional SU(1,1) dynamical invariant that guarantees…
Orbital angular momentum radiation and polarization of relativistic electrons in magnetic fields
Ziqiang Huang, Qi Meng, Xuan Liu +6
While spin polarization from synchrotron radiation is well established, the polarization of orbital angular momentum (OAM) in such radiative processes remains elusive. We study rad…
Relativistic quantum mechanics of charged vortex particles accelerated in a uniform electric field
Qi Meng, Ziqiang Huang, Xuan Liu +6
The relativistic quantum-mechanical description of a charged Laguerre-Gauss beam accelerated in a uniform electric field has been fulfilled. Stationary wave eigenfunctions are rigo…
